• Connecting Java se Client to Glassfish

  - by Henrik Bierbum Bacher

  We are having some difficulties connecting our Java SE standalone client with the EJB module deployed on a remote GlassFish server. Pointers to how we are supposed to connect our client would be appreciated. The client code we currently has to get the initial context: props.setProperty("org.omg.CORBA.ORBInitialHost", "*remotehost*"); props.setProperty("org.omg.CORBA.ORBInitialPort", "portNumber"); javax.naming.InitialContext ic = new javax.naming.InitialContext(props); *We have tried several different port numbers; 3700, 7676, 8080.. The closest we are getting, got us the error: "Error in GIOP magic". I read that jms are using port 7676 as a broker port for a bunch of dynamically generated ports, but can't figure out how to specify those ports in order to create proper port-forwards.

• Simulating a mouse button click in Windows

  - by Ncarlson

  Hi everyone, I'm writing Remote Desktop clone in C++ using QT. So far I'm able to move the mouse cursor around fine. QT has a nice setPos function for that. However, I'm a bit lost as to what API/Library to use for simulating mouse button clicks. One method I'm aware of is to send the WM_(event) to a window using the window's HWND. However, I was hoping there was a more salient method for taking complete control over a mouse. Is there any other way to tell the operating system that the left mouse button has been clicked? Thanks.

• Simulating a cookie-enabled browser in PHP

  - by Itamar Benzaken

  How can I open a web-page and receive its cookies using PHP? The motivation: I am trying to use feed43 to create an RSS feed from the non-RSS-enabled HighLearn website (remote learning website). I found the web-page that contains the feed contents I need to parse, however, it requires to login first. Luckily, logging in can be done via a GET request so it's as easy as fopen()ing "http://highlearn.website/login_page.asp?userID=foo&password=bar" for example. But I still need to get the cookies generated when I logged in, pass the cookies to the real client (using setcookie() maybe?) and then redirect.

• How to set a local image in pynotify?

  - by George Edison

  If I run the following in python in Ubuntu 10.04: >>> import pynotify >>> p = pynotify.Notification ("Notice","","/home/george/Pictures/test.png") >>> p.show() true The message displays as expected, except the image does not appear in the OSD. How can I display a local image? In fact, for what I need, it would be better if I could display a remote image. (via HTTP) How can I do that?

• How to set up an Android source repo while hosting the git trees as private repositories on github?

  - by gby

  Hello there, I am trying to set up a private repository of Android source code while hosting the git trees on github as private repos. I have no problem changing the manifest.xml file to point to public git trees hosted on github in the same way that CynagonMod does, but when trying to point to private repos I get the following error when trying "repo sync": Initializing project username/android_external_webkit ... fatal: The remote end hung up unexpectedly error: Cannot fetch username/android_external_webkit Where username/android_external_webkit is of course a private github repo of the same name. I understand the error occurs since I did not specify my user name and credentials to github, but I fail to see how to do it in the manifest.xml with repo. Any ideas? Thanks! Gilad

• Android: making a custom ListView independent of adapters ?

  - by wei

  I am adding a local database as a cache to a remote web service in my android application to answer queries. I used ArrayAdapters before for list views to display the results from the web service. Now with a database cache, the result could be either a Cursor(from database) or a List(from web), which means the adapter can be CursorAdapter or ArrayAdapter too. Creating two adapters for one query doesn't seem to be a good idea. So I am wondering what would be the best way to refactor my current code to add this database feature? Thanks,

• Debug Linux kernel pre-decompression stage

  - by Shawn J. Goff

  I am trying to use GDB to debug a Linux kernel zImage before it is decompressed. The kernel is running on an ARM target and I have a JTAG debugger connected to it with a GDB server stub. The target has to load a boot loader. The boot loader reads the kernel image from flash and puts it in RAM at 0x20008000, then branches to that location. I have started GDB and connected to the remote target, then I use GDB's add-symbol-file command like so: add-symbol-file arch/arm/boot/compressed/vmlinux 0x20008000 -readnow When I set a breakpoint for that address, it does trap at the correct place - right when it branches to the kernel. However, GDB shows the wrong line from the source of arch/arm/boot/compressed/head.S. It's 4 lines behind. How can I fix this? I also have tried adding the -s section addr option to add-symbol-file with -s .start 0x20008000; this results in exactly the same problem.

• How do I write my own desktop sharing application in java ?

  - by nomemory

  Hello I want write my own desktop sharing application in Java. The application should have some very default features: Capture screen; Allow a remote connected user to click / edit fields. I was thinking to use Java Robot class for mouse movements / key pressing. The problem is i don't know what screen capture strategy to use. Should I make sequentially screen captures (on the hosting computer) every second, and send those captures with UDP via network, so that the clients can intercept the data-grams ? Isn't this a little overkill for the network ? What other strategies are available ? (Except trying an already existing app). PS: If necessary I can even write native code using JNI (still that's the last thing I planning to do).

• Why can't I save CSS changes in FireBug?

  - by Dean

  FireBug is the most convenient tool I've found for editing CSS - so why isn't there a simple "Save" option? I am always finding myself making tweaks in FireBug, then going back to my original .css file and replicating the tweaks. Has anyone come up with a better solution? EDIT: I'm aware the code is stored on a server (in most cases not my own), but I use it when building my own websites. Firebug's just using the .css file FireFox downloaded from the server, it knows precisely what lines in which files its editing, I can't see why there's not an "Export" or "Save" option which allows you to store the new .css file. (Which I could then replace the remote one with). I have tried looking in temporary locations, and choosing file-save and experimenting with the output options on FireFox, but I still haven't found a way. Here's hoping someone has a nice solution... EDIT 2: The Official Group has a lot of questions, but no answers.

• What does it mean when git pull causes a conflict but git pull --rebase doesn't?

  - by Jason Baker

  I'm pulling from a repository that only I have access to. As far as I know, I've only pushed to it from one repository. A couple of times, I've pulled from it and gotten this: To [email protected]:tsched_dev.git ! [rejected] master -> master (non-fast-forward) error: failed to push some refs to '[email protected]:tsched_dev.git' To prevent you from losing history, non-fast-forward updates were rejected Merge the remote changes before pushing again. See the 'Note about fast-forwards' section of 'git push --help' for details. Generally, that just means that I have to do a git pull (although all the changes should be fast-forwardable). When I do a git pull, I get conflicts. If I do a git pull --rebase, it works fine. What am I doing wrong?

• Lightweight PHP server to bundle with application?

  - by munchybunch

  Does there exist some sort of PHP server that can be bundled with a locally-deployed application? It sounds wonky, but the end result is I can't use a remote web server to do anything. Clients will be downloading a package, and the plan is to use a Java backend that reads from a flat file. The flat file contains settings and is modified through a GUI written in HTML/JS, and this is where the server would come in. The forms in HTML should be able to submit to the server, which does a simple file write to the flat file. Is there any simple, lightweight server that has that simple feature? When running the executable for the application, it would start the installation process for the server before moving the web GUI files to the appropriate locations. Note that I'm doing this for a client, so I can't quite change the reqs and would rather not discuss their effectiveness. I would be ever thankful if people had suggestions for the server though!

• Restart nginx without sudo?

  - by tesmar

  So I want to be able to cap:deploy without having to type any passwords. I have setup all private keys so I can get to the remote servers fine, and am now using svn over ssh, so no passwords there. I have one last problem, I need to be able to restart nginx. Right now I have sudo /etc/init.d/nginx reload. That is a problem b/c it uses the capistrano password, the one I just removed b/c I am using keys. Any ideas on how to restart nginx w\out a password?

• Keeping iPhone application in sync with GWT application.

  - by Reflog

  Hi, I'm working on an iPhone application that should work in offline and online modes. In it's online mode it's supposed to feed all the information the user enters to a webservice backed by GWT/GAE. In it's offline mode it's supposed to store the information locally, and when connection is available sync it up to the web service. Currently my plan is as follows: Provide a connection between an app and a webservice using Protobuffers for efficient over-the-wire communication Work with local DB using Core Data Poll the network status, and when available sync the database and keep some sort of local-db-to-remote-db key synchronization. The question is - am I in the right direction? Are the standard patterns for implementing this? Maybe someone can point me to an open-source application that works in a similar fashion? I am really new to iPhone coding, and would be very glad to hear any suggestions. Thanks

• creating a wordpress dev enviornment and uploading to production

  - by Jeff

  I am an old school java developer who is considering a using wordpress. I'm used to developing locally on my PC (yeah yeah not even a mac) and then ftping my files up to a production environment on a remote server. My high level review of wordpress gives me the impression that typically there is no concept of lower environments and that all updates occur directly in production. Is this the case? If not, can someone explain how one goes about uploading the files to a web site? Thanks, Jeff

• Control Philips Living Colors using PC

  - by CrazyChris

  Hi guys, is there a way (hardware/software-combination) that I can use to control one or more "Philips Living Colors" lamps using a PC - e.g. a USB-stick that acts as the "remote". This way i could control the lamp through software (e.g. a web-app - over iPhone / remotely) or even create what Philips builds into some of their TVs and calls "ambilight" (graphics driver detecting the main color to control the lamp). I guess this is more like a hardware than a software question - but I couldn't find anything about this online and I'm sure not to be the first to have come up with this idea right when I unpacked my LivingColors lamp yesterday ;) Any idea/hint is appreciated. -chris

• validates_uniqueness_of...limiting scope - How do I restrict someone from creating a certain number

  - by bgadoci

  I have the following code: class Like < ActiveRecord::Base belongs_to :site validates_uniqueness_of :ip_address, :scope => [:site_id] end Which limits a person from "liking" a site more than one time based on a remote ip request. Essentially when someone "likes" a site, a record is created in the Likes table and I use a hidden field to request and pass their ip address to the :ip_address column in the like table. With the above code I am limiting the user to one "like" per their ip address. I would like to limit this to a certain number for instance 10. My initial thought was do something like this: validates_uniqueness_of :ip_address, :scope => [:site_id, :limit => 10] But that doesn't seem to work. Is there a simple syntax here that will allow me to do such a thing?

• How can I "git log" only code published to trunk?

  - by Russell Silva

  At my workplace we have a "master" trunk branch that represents published code. To make a change, I check out a working copy, create a topic branch, commit to the topic branch, merge the topic branch into master, and push. For small changes, I might commit directly to master, then push. My problem is that when I use "git log", I don't care about my topic branches in my local working copy. I only want to see the changes to the master branch on the remote, shared git server. What's more, if I use --stat or -p or one of their friends, I want to see the files and changes associated with the merge commit to master, not associated to their original branch commits (which, like I said, I don't want to see at all). How do I go about doing this?

• Git to SVN trouble

  - by Kevin

  My boss has a Perforce repository for which he wants to make a read-only copy available on Sourceforge via subversion. He had a perl script which would do this but it's no longer functioning (we don't want to try debugging it yet) and it's really not that great anyway. So an alternate solution is to pull the perforce repo into git as a remote ref, which I have already done successfully (including all the proper commit details and authors), now the trouble I'm having is pushing it out to a separate SVN repository. I can make it start the commit process with "git svn dcommit --add-author-from", but the problem is even though the correct author appears at the end of the commit message the "real" author committing is my machine's user. I want to preserve the real author with the commit, and I'd also like to preserve the original timestamps as well. Is anyone familiar with how I could accomplish this?

• What goes between SQL Server and Client?

  - by worlds-apart89

  This question is an updated version of a previous question I have asked on here. I am new to client-server model with SQL Server as the relational database. I have read that public access to SQL Server is not secure. If direct access to the database is not a good practice, then what kind of layer should be placed between the server and the client? Note that I have a desktop application that will serve as the client and a remote SQL Server database that will provide data to the client. The client will input their username and password in order to see their data. I have heard of terms like VPN, ISA, TMG, Terminal Services, proxy server, and so on. I need a fast and secure n-tier architecture. P.S. I have heard of web services in front of the database. Can I use WCF to retrieve, update, insert data? Would it be a good approach in terms of security and performance?

• How do I parse an XML file that's on a different web server?

  - by Tim

  I have a list of training dates saved into an XML file, and I have a little javascript file that parses all of the training dates and spits them out into a neatly formatted page. This solution was fine until we decided that we wanted another web-page on another sever to access the same XML file. Since I cannot use JavaScript to parse an XML file that's located on another server, I figured I'd just use an ASP script. However, when I run this following, I get a response that there are 0 nodes matching a value which should have several: <% Dim URL, objXML URL = "http://www.site.com/feed.xml" Set objXML = Server.CreateObject("MSXML2.DOMDocument.3.0") objXML.setProperty "ServerHTTPRequest", True objXML.async = False objXML.Load(URL) If objXML.parseError.errorCode <> 0 Then Response.Write(objXML.parseError.reason) Response.Write(objXML.parseError.errorCode) End If Response.Write(objXML.getElementsByTagName("era").length) %> My question is two-fold: Is there are a way I can use java-script to parse a remote XML file If not, why doesn't my code give me the proper response?
